Highly reflective metallic surfaces are among the most challenging inspection targets in machine vision. Reflections obscure details; defects often become visible only from certain angles, and the quality of manual visual inspections fluctuates throughout the workday.

A measurement isn’t only a number. It’s a number obtained by an instrument in a physical state.
That distinction becomes critical when the instrument moves, bends, conforms to a surface, or relies on software to correct its own geometry. A rigid gauge can often treat its working…
Finding something underground is one thing. Giving a project team information they can actually use is another.
A technician might pick up a signal with an electromagnetic locator. A ground-penetrating radar scan might show an anomaly running through a proposed work area. An old…
For decades, reverse engineering was a tool reserved for large manufacturers. Aerospace manufacturers leaned on it to keep aging fleets in service when computer-aided design (CAD) data were missing. Defense contractors relied on it to re-create components that had long outlived their original…
When doctors need to deliver precise doses of medicine on a strict schedule, they often administer it intravenously. Intravenous drug delivery methods need to carefully control the flow of medicine into a patient. Knowing the medicine’s flow rate—or the volume of fluid flowing into the patient…
Quality control processes are never about single-inspection scenarios—and yet most inspection systems are. Inspection requirements constantly shift between part dimensions, hard-to-reach areas, quick validations, and precise feature measurements, creating daily challenges for QC professionals.…
